Harper is in Memphis before Christmas, visiting her sister and family after three years working at museums in Europe. Visiting Graceland with her two nieces, Harper meets a single dad of three kids and is offered a job as temporary nanny.

Harper returns to Memphis after working in Europe for three years. She is back to visit her sister and her family, but also to interview for a job at an art museum at their branch in London. While waiting for news about the job, she accepts a request to step in as a nanny for a single father, Owen, and his three children. She also gets involved in an exhibition at her former workplace, the Elvis Presley Museum in Graceland. Harper comes in and nudges against Owen's well-established routines, causing him to reassess certain aspects of his life.
